1. Ingestion:
* Plastic: Animals often mistake plastic bags, bottles, and other litter for food. When ingested, it can block their digestive systems, leading to starvation or internal injuries. This is a major problem for sea turtles, who often mistake plastic bags for jellyfish.
* Food wrappers: Food wrappers, like candy wrappers and chip bags, can also be harmful. Animals may ingest them, mistaking them for food, which can cause blockages or internal injuries.
* Other items: Animals can also ingest other types of litter, such as cigarette butts, straws, and even metal scraps, leading to similar problems.
2. Entanglement:
* Fishing line: Discarded fishing line can entangle animals, causing them to drown, starve, or become injured. Seabirds and sea turtles are particularly vulnerable to this.
* Plastic six-pack rings: These rings can become trapped around an animal's body parts, restricting their movement and causing injuries or death.
* Other items: Other types of litter, like discarded ropes or bags, can also cause entanglement problems.
3. Habitat destruction:
* Litter can pollute water sources: Litter can leach harmful chemicals into waterways, poisoning fish and other aquatic animals.
* Litter can accumulate in animal habitats: Litter can pile up in areas where animals live, making it difficult for them to find food and shelter.
* Litter can impact food sources: Litter can contaminate food sources, making them unsafe for animals to eat.
4. Pollution:
* Litter can release harmful toxins: Some types of litter, like plastic and metal, can release toxic chemicals into the environment, harming animals and humans.
* Litter can attract pests: Litter can attract pests, such as rodents and insects, which can spread diseases and create other problems.
It's crucial to understand that even seemingly harmless litter, like a candy wrapper or a cigarette butt, can have devastating consequences for wildlife. By disposing of our waste responsibly, we can help protect animals and keep our environment clean.
